Owning standards and instruments with traceable calibrations is
necessary but not sufficient for making traceable calibrations with

I looked at the listing you posted. The unit looks very nice. However, the
units are selling in the $150 - $250 range, although I note some of the
units you linked to have sold for the price asked.
There has been considerable discussion on the list about the 3457A and some
differences

On the fact of it, the device would give one a reasonly high

Let's assume that it is still working exactly the same as it was
